Description

  The present invention relates to a seismic reinforcement wall retrofitted to an existing building.

  As an earthquake-proof reinforcement wall retrofitted to an existing building, there exists a thing disclosed by patent document 1, for example. The technology of Patent Document 1 is a technology in which a plurality of lightweight C-shaped steels are stacked in the vertical direction to form an anti-seismic reinforcement wall, and the flanges of lightweight C-shaped steels adjacent to each other in the vertical direction are fastened with high-strength bolts or the like. So we are trying to integrate.

JP-A-11-293950

  In the seismic reinforcement wall of Patent Document 1, it is necessary to overlap the flanges of adjacent lightweight C-shaped steels, but the lightweight C-shaped steel flanges are arranged so as to intersect the construction surface to be reinforced, The situation where the two flanges are overlapped can be observed from the indoor side, giving a profound impression to the building user. Moreover, in the earthquake-proof reinforcement wall of patent document 1, since many high strength volt | bolts will protrude on the upper and lower sides of a flange, combined with the two flanges being piled up, the aesthetics of indoor space are given. There is a risk of damage.

  From such a viewpoint, an object of the present invention is to provide a seismic reinforcing wall that is configured by combining a plurality of members and that can relieve a heavy impression.

  The present invention for solving the above problems is a seismic reinforcement wall comprising a plurality of wall plates arranged side by side along the construction surface to be reinforced, and a connecting member that joins the wall plates adjacent to each other on the left and right. The connecting member has a connection plate portion arranged along the composition surface and a stiffening plate portion arranged so as to intersect the composition surface, and the wall plate overlaps the connection plate portion. The wall surface plate and the connection plate portion are frictionally joined by a high-strength bolt that penetrates the wall surface plate and the connection plate portion.

The “structural surface to be reinforced” is a virtual vertical plane surrounded by a frame of an existing building (column, beam, wall, floor slab, etc.).
In the present invention, the wall plate is overlapped with the connection plate portion of the connecting member, and both are friction-joined by high-strength bolts. However, the overlapping portion (wall plate and connection plate portion) is along the surface. Since it arrange | positions, it will become difficult to observe a mode that the wall surface board and the connection plate part were overlapped from the indoor side. Moreover, in this invention, since the structure which overlaps stiffening plate parts is not employ | adopted, the high strength volt | bolt for frictionally joining stiffening plate parts is unnecessary. The stiffening plate portion is a structural element that suppresses out-of-plane buckling of the connection plate portion and suppresses out-of-plane buckling of the wall plate joined to the connection plate portion.

  The connecting member includes a lower end plate portion joined to lower ends of the connection plate portion and the stiffening plate portion, and an upper end plate portion joined to upper ends of the connection plate portion and the stiffening plate portion. Also good. In this way, when the plurality of connecting members are arranged, the plurality of lower end plate portions are connected in the left-right direction and the plurality of upper end plate portions are connected in the left-right direction. Can be used as an outer peripheral frame.

  The wall plate may be superimposed on either the front surface or the rear surface of the connection plate portion. However, if the wall plate is superimposed on the front surface of the connection plate portion, the connection plate portion will be covered with the wall plate. It has a cleaner appearance than when it is superimposed on the rear surface of the plate portion. When the wall plate is superimposed on the front surface of the connection plate portion, the stiffening plate portion may be protruded to the front side of the wall plate between the adjacent wall plates.

  When a window is provided on the seismic reinforcement wall, a unit with a window formed with a window may be combined. The configuration of the unit with a window is not limited, but the vertical frame plate portions disposed on the left and right sides of the window portion, the brace portions disposed between the adjacent vertical frame plate portions, and the outside of the vertical frame plate portion. If a thing provided with the end plate part arrange | positioned along a side surface is utilized, since it will become possible to transmit a shear force by a brace part, it will become possible to form a big window part.

  When joining the unit with a window and the wall plate, the wall plate is overlaid on the end plate portion, and the wall plate and the wall plate by the high-strength bolt that penetrates the wall plate and the end plate portion. The end plate portion may be friction bonded. If it does in this way, it will become difficult to observe a mode that the wall plate and the end plate part were piled up from the indoor side.

  A makeup back plate that covers the high-strength bolt may be disposed on the front side of the wall surface plate, and a shelf plate may be provided on the front surface of the makeup back plate. If it does in this way, it will become possible to use an earthquake-proof reinforcement wall as a bookshelf or a display shelf. Moreover, since the high-strength bolt is covered by the decorative back plate, a clean appearance is obtained. Note that the stiffening plate portion of the connecting member and the vertical frame plate portion of the windowed unit can be used as a book end or the like.

  When a plurality of wall surface plates are arranged side by side, an intermediate horizontal member for joining the wall surface plates adjacent to each other in the vertical direction may be disposed. In this case, the intermediate horizontal member uses a vertical plate portion disposed along the composition surface and a horizontal plate portion disposed so as to intersect the composition surface, and the vertical plate portion is used. It is desirable that the wall surface plate and the vertical plate portion be friction-joined with a high-strength bolt that penetrates the wall surface plate and the vertical plate portion.

  According to the seismic reinforcement wall according to the present invention, it is possible to relieve a heavy impression.
